I don’t want to derail the food budget / do you eat out thread to a tipping thread, of which there are already plenty, but I don’t think tipping affects the overall budget question of whether people can / do eat out or not.
Those of us discussing tipping and app fees do so from the privileged perspective of already being able to eat out in some format without budget question that is the whole point of the OP.
I think the extra “service” fee issue of apps has also been beaten to death elsewhere, lol.
